i have 2 views and both are table views
1st view
list is there, so when user click on particular cell, i want to take the text of selected cell and store into variable and push 2nd view
e.g. stringVariable = cell.text
2nd view
now i want to set title of view by using stringVariable variable
e.g. self.title = stringVariable;
i hope some one know this issue
thank you in advance
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Save text of the selected cell:
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
stringVariable = cell.textLabel.text;
// load next view and set title:
MyView *nextView = [[MyView alloc] initWithNibName:#"MyView" bundle:nil];
nextView.title = stringVariable;
[self.navigationController pushViewController:nextView animated:YES];
}
You must be using some array data to fill the table Views.
eg.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
TableItem * tableItem = [tableItems objectAtIndex:indexPath.row];
UILabel mainLabel = [[UILable alloc] initWithFrame:()];
mainLabel.text = tableItem.name;
[cell.contentView addSubView:mainLabel];
[mainLabel release];
return cell;
}
Similarly you should use the same array to get the required item, which is selected
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
TableItem * tableItem = [tableItems objectAtIndex:indexPath.row];
OtherViewController * otherViewController = [[OtherViewController alloc] init];
otherViewController.name = tableItem.name;
[self.navigationController pushViewController:otherViewController animated:YES];
[otherViewController release];
}

Can you please help me to do this one?
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [popOveritem objectAtIndex:indexPath.row];
[cell.textLabel setFont:[UIFont systemFontOfSize:10.05f]];
cell.imageView.image = [UIImage imageNamed:[popimage objectAtIndex:indexPath.row]];
NSLog(#"cellCOntent%#",cell.textLabel.text);
UIView *cellbgColorView = [[[UIView alloc] init]autorelease];
[cellbgColorView setBackgroundColor:[UIColor colorWithRed:40/255.0 green:128/255.0 blue:184/255.0 alpha:1.0]];
cell.selectedBackgroundView = cellbgColorView;
tableVIEW.scrollEnabled = NO;
return cell;
first time the tableview will show one record and when i click to the button appeared in the view will add another row at the top of the table view?
take a look at the below code hope it gives you what you need
viewcontroller.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UIAlertViewDelegate,UITableViewDataSource,UITableViewDelegate>
{
IBOutlet UITableView *tblTest;
NSMutableArray *arrData;
int increment;
}
-(IBAction)onClickAdd:(id)sender;
#end
viewcontroller.m
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
arrData = [[NSMutableArray alloc] initWithObjects:#"Data 1", nil];
increment = 1;
}
-(IBAction)onClickAdd:(id)sender
{
increment++;
NSString *strInsertData = [NSString stringWithFormat:#"Data %d",increment];
[arrData insertObject:strInsertData atIndex:0];
[tblTest reloadData];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [arrData count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.accessoryView = nil;
cell.selectionStyle = UITableViewCellSelectionStyleGray;
}
cell.textLabel.text = [arrData objectAtIndex:indexPath.row];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
Here is my problem :
I created a .xib with some label. I created a UITableViewController like this :
- (void)viewDidLoad {
[super viewDidLoad];
dataToShow = [[NSArray alloc] initWithObjects:#"cave",#"garage",nil];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [dataToShow objectAtIndex:indexPath.row];
return cell;
}
The numberOfSectionInTableView and numberOfRowInSection are filled correctly, when running the programe the list shows as it should. I would like now, depending on which row the user click in the table view, to load the xib i created and fill the labels with text. Is that possible and if it is, how do I pull it off ? Thanks
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
yourNextViewController *nextViewXib = [[yourNextViewController alloc]initWithNibName:#"yourNextViewController" bundle:nil];
nextViewXib.yourLable.text=[dataToShow objectAtIndex:indexPath.row];
[self.navigationController pushViewController:nextViewXib animated:YES];
[nextViewXib release];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSLog(#"selected row:%d",indexPath.row);
}
//in this mathod you get will row is calling..
I made a demo empty app and add a navigation controller with the view
UINavigationController *navBar = [[UINavigationController alloc]initWithRootViewController:objFirstViewControllerViewController];
[self.window addSubview:navBar.view];
After it i add a table view on the first view controller like this .
UITableView* demotableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320, 400) style:UITableViewStylePlain];
demotableView.delegate = self;
demotableView.dataSource = self;
[self.view addSubview:demotableView];
and the delegate function of the table view and main cell for row function like this way
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.textLabel.text = #"Hello this is sample text";
cell.textLabel.minimumFontSize = 12;
cell.textLabel.adjustsFontSizeToFitWidth = TRUE;
cell.textLabel.font = [UIFont fontWithName:#"Copperplate" size:18];
return cell;
}
But when i scroll on my table or click any cell to go on the next view it just crash and give these two error on clicking and scrolling respectively.
[__NSCFArray tableView:didSelectRowAtIndexPath:]
[__NSCFDictionary tableView:cellForRowAtIndexPath:]
I don't understand what is getting wrong this code it have been working with the prior os properly
Any body can help please ?
Here is the code for did select row
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
Second *anotherViewController = [[Second alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:anotherViewController animated:YES];
}
and no of row is this one
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 15;
}
Actually I misused the ARC what are the changes I made to make the app run successfully actually it was crashing due to memory leak I reference the class in delegate with local object but the it got released when it tried to add the data on it and when table's delegate and datasource try to add the things in the current class it was released and it throw message from those message instances, I was stuck because I was thinking it is happening due to me having taken an empty kind of application but after adding the lines below in the delegate class I got the problem solved.
What I did in the delegate class in the .h file:
FirstViewControllerViewController *objFirstViewControllerViewController;
#property (strong, nonatomic) FirstViewControllerViewController *objFirstViewControllerViewController;
Then my table started behaving properly and all things that I was having problem in.
Replace your code by this and try:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = #"Hello this is sample text";
cell.textLabel.minimumFontSize = 12;
cell.textLabel.adjustsFontSizeToFitWidth = TRUE;
cell.textLabel.font = [UIFont fontWithName:#"Copperplate" size:18];
return cell;
}
Hope this helps.
Please try this....
add your table view like this..
productList = [[UITableView alloc] initWithFrame:CGRectMake(0,102, 320, 267) style:UITableViewStylePlain];
productList.delegate = self;
productList.dataSource = self;
productList.backgroundColor = [UIColor clearColor];
[self.view addSubview:productList];
and add these methods....
#pragma mark Table view data source
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return (your row count);
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]autorelease];
}
// Configure the cell.
cell.textLabel.text = #"Title";
cell.detailTextLabel.text = formattedString;
cell.detailTextLabel.textColor = [UIColor darkGrayColor];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
Second *anotherViewController = [[Second alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:anotherViewController animated:YES];
}
Since you have set demotableView.delegate = self;
you have to implement the tabelView: didSelectRowAtIndexPath: function which solves the crash on selecting(on Click) a Cell.
To resolve the crash of scrolling, you hav to implement
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
method.
P.S: In the cellForRowAtIndexPath:, all the lines except cell.textLabel.text should be inside
if(cell == nil){
}
and please follow proper maemory management rules
I have a working table view on my iphone app, and am implementing a second view using navigationController.
But when I try to select a cell on the initial view, it does not respond i.e. no highlighting in blue, no selection.
Can anyone suggest what I might have missed, or what is responsible for actually selecting the cell when the user taps it?
OK thanks for your suggestions - still no luck. here is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
[cell setSelectionStyle: UITableViewCellSelectionStyleBlue];
UIView *selectionView = [[[UIView alloc] init] autorelease];
selectionView.backgroundColor =[UIColor redColor];
cell.selectedBackgroundView = selectionView;
}
// format text
cell.textLabel.font = [UIFont fontWithName:#"Arial" size:12];
cell.textLabel.text = [tableArray objectAtIndex:indexPath.row];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//NSUInteger row = indexPath.row;
//[DetailView selectRowAtIndexPath:indexPath animated:YES];
//UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath.row];
//[cell setSelectionStyle: UITableViewCellSelectionStyleBlue];
DetailView *detailView = [[DetailView alloc] initWithNibName:#"DetailView" bundle:nil];
[self.navigationController pushViewController:detailView animated:YES];
[DetailView release];
}
May be you have done this line of code in cellForRowatIndexPath::
cell.selectionStyle = UITableViewCellSelectionStyleNone;
If yes, then replace it with either of these:
cell.selectionStyle = UITableViewCellSelectionStyleGray;
or
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
Without looking at your code I would say you have to add this line in your cellForRowAtIndexPath delegate method.
[cell setSelectionStyle:UITableViewCellSelectionStyleBlue];
And also you have to implement this delegate method which gets called when you tap on cell of UITableView..
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
I am using below code in implementation file. The issue is when I click on a row it does not take me to another view?
please help
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 3;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [NSString stringWithFormat:#"Vehicle List %d", [indexPath row]+1];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (self.vehic == nil) {
Vehicle *vehicle = [[Vehicle alloc] initWithNibName:#"Vehicle" bundle:[NSBundle mainBundle]];
self.vehic = vehicle;
}
[self.navigationController pushViewController:self.vehic animated:YES];
}
For going to another View you should handle this method Correctly :-
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
// on click on any row now it will go to Another View, let the other view be SecondViewController's View
SecondViewController *viewController = [[SecondViewController alloc]initWithNibName:#"FirstViewController" bundle:nil];
[self presentModalViewController:viewController animated:YES];
}
That's all. If you face any problem then tell me. :)
